Phoseon Technology is expanding its Hillsboro headquarters and factory by 50 percent.

A Hillsboro company that makes semiconductor light for industrial applications says it will expand its factory by more than 50 percent in anticipation of continued growth.

Phoseon Technology's work force has grown from 125 to 175 over the past two years, the vast majority of them at its Hillsboro headquarters, according to marketing communications manager Marine Faucher. The company makes ultraviolet LED lamps used in industrial curing.

Founded in Oregon 16 years ago, privately held Phoseon makes ultraviolet LED lights that dry adhesives, coatings and ink. It substitutes for heat or evaporation, which can be slower or more energy-intensive. A common alternative, arc lamps, use mercury - an extremely hazardous material.

Phoseon is expanding its Hillsboro site to 35,000 square feet and says its revenue is growing at an annual rate of 25 percent. The company says it is profitable and has been for several years.

Oregon has more than 190,000 manufacturing jobs, up 20 percent since 2010. But the state still has 20,000 fewer factory jobs than it did in 2006, before the Great Recession.

Phoseon raised $9.2 million through 2006 and hasn't reported any subsequent investment. The current expansion reflects anticipated further growth, according to Faucher, but she declined to say just how many more jobs the company expects to add.

"The industry and the business is definitely doing very well," she said. "We really expect it to continue to grow."

Correction: Phoseon says its work force has grown by 50 over the past two years, not grown from 50 over the past two years as this article originally stated. Also, phrasing in the headline has been changed to indicate that Phoseon does not make the LEDs in its lamps.
